TATES DEVICE FOR VASSORTING ARTICLES RELA- TIVE TO TH R VARIATION IN SIZE Shubel A. Foster, Ferndale, Mich. Application March 23,1931. Serial N6.- 524,601 4 solai s, (01. 209-32) Myinvention' relates to an apparatus for gaug ing and assorting like elements in accordance with their respective size, as shown in the accompanying drawing and more particularly de- 1 5 scribed in the following specification and claims.

The primary object-of the present invention is to provide a simple and relatively inexpensive device which is'adaptedto automatically assort I articles of the same character into groups according to theirsize. In the-present instant'the disclosure shows a device designed to assort rollers according to their respective diameters and to deposit them into-a pluralityof containers respectively designed to receive the sev- A further object of the invention is toprovide anapparatus in which therollers are passed between a pair'of opposing-elements, one of which isfi'xed and the other automatically adjustable '20 to permit the passage 'of rolls of predetermined for like articles of the same size.

A further object of the invention is the simple and inexpensive means employed for automatically obtaining the adjustment of the opposing V elements between which rollers of varying diameters pass for delivery to the respective receptacles for rollers of predetermined'siza- With the foregoing and other objects in View which will appear as the description proceeds, the invention further resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understoodtha't'changes may be made in the precise embodiment of the invention herein disclosed without departing from In the drawing accompanying this specification: 1

Figure l is a plan View of the apparatus, showing a crank arm as a means for actuating the device,-preferably driven by mechanical means. Figure 2 is a side elevation of the apparatus with parts broken away to disclose the mechanism directly back of the parts removed,-other parts being shown in section.- V Figure 3 is a fragmentary plan view of a detail of the distributor and means for rotating the same,with parts shown in section, taken on or about line 33 of Figure 2.

Figure 4 is a plan view with parts in section,--

taken on or about line 4-4 of Figure 2,-showing the conduits which-direct the rollers of different iameters to their respective receptacles as deliveredthereto bythe distributor. p Figure '5 are-detail views of a plurality of cams of like diameter and configuration, showing them in respectively"different positions in relation to each other on the same supporting cam shaft, with adjustable means adaptedto be acted upon by thecams' for automatically changing the size of the gap through which the rolls pass for distribution. 1

Referring now to the reference characters in which the same characters represent like parts in the different viewsu The base 1 of the apparatus is provided with a pair of projecting lugs 2, 2, from which extend in opposing relation cone-shaped trunnions 3, 3, on which is mounted a rocking frame 4, intermediate of its length. l

The rocking lever 4 has a projecting element 5 formed with a convex end in opposing spaced re- 7 lation to a similar projecting element 6, adjustably secured to a fixed transversely extending wall A, integral with the base frame.

Adjustably mounted in the cross-member B, at the opposite end of the rocking frame 4 are adjustable shoes or screws 7, 8, 9 and 10, which project through the lower face of the cross-member I B, that they may ride upon the respective cams 12, 13, 14 and 15, mounted on the cam shaft 17, in spaced relation to each other. Set screws 7 8 9 and 10 serve'to secure the shoes, or screws 7, 8, 9 and 10 when-adjusted.

It will be noted that the respective cams 1215 are of the same size and configuration for economy of construction, and that the shoes or screws 7, 8,9 and 10 are respectively adjusted to a greater or lesser extent to secure a relatively different adjustmentof the rocking lever and thereby a varying gap to permit the passage of rollers 5" of different size between the projecting element 5, and the opposing projecting element 6, attached to the cross-member B of the base.

In Figure 5 the cams 12-13--14--15 are shown in their respective relation to each other when on the cam shaft 17, and also the adjustable shoes or screws 14, 15, 1 6 and 1'7, for changing the size of the discharge opening between the projecting elements 5 and 6, previously described.

While I have illustrated only four cams, it will 7 be obvious that a greater or less number of cams may be provided as desired. Cam 12 and its adjustable shoe '7 controls the initial size of the discharge orifice.

shifted by the shoes 7, 8, etc. riding on the respective cams 12, 13, etc. are indicated in dotted lines in Figure 5,-this movementtransmitted to the projecting element carried by the rocking lever 5 changes the relative size of the discharge gap between the projecting element 5, secured to the rocking frame, and the opposing fixed projecting element 6, secured to the base frame, as will be readily understood.

The third and fourth group in Figure 5, show respective adjustments to provide a discharge opening or orifice, different in size to those produced by the cam 12 and shoe '7, and by the cam ,13 and shoe 8.

15 l The distributor 16 and cam shaft 1'7, are rotatively synchronized, thus when a roller 18, is passed through the discharge gap between the projecting elements 5 and 6,-it will fall into tube 20,and carried thence by the distributor 16, it

20 passes from tube 20 into pocket 21, and out through passage 22 to the proper receiving receptacle, not shown.

The cam shaft 17, while shown in the drawing as actuated by a crank 21, is preferably driven by a motor.

On the end ofthe cam shaft is a gear 23, which drives the train of gears 24-2526-27. Gears 25 and 26 are carried by a shaft 28, journaled in a bracket projecting from the frame of the machine. Gear 27 is mounted on the lower end of shaft 29, journaled in a bracket extending from the frame of the machine. Mounted on the shaft 29 is the distributor 16,-carrying tube 20,- which when rotated through the train of gears 5 directs the roller 18 from tube 20, into the passage leading to its proper receptacle.

Having thus described my invention, what I claim is;

1. A sizing machine comprising sizing elements; means for gradually increasing the distance between said elements so as to permit an article to pass therebetween; a plurality of receiving members; and a selecting chute movable relatively to the sizing elements and synchronously with said first mentioned means for conducting to a selected receiving member the article passing the sizing elements, one end of said chute being always in communication with the sizing gap, the other end passing successively into registration with the receiving members.

2. A. sizing machine comprising sizing elements; a rocking member carrying one of said sizing elements; means for tilting said rocking member to gradually increase the distance between the sizing elements to permit articles of different {i'auge to pass between said sizing elements; a plurality of receiving members; and a selecting chute; movable relatively to the sizing elements and synchronously with said means for tilting said rocking member, for conducting to a selected receiving member the article passing the sizing elements, one end of said chute being always in communication with the sizing gap, the other passing successively. into registration with the receiving members.

, 3. A sizing machine, comprising sizing elements; a rocking member carrying one of said sizingelements; a plurality of cams mounted in s spaced relation upon a drive shaft; a plurality of adjustable screws supported in a wall of the rocking member and adapted to be acted upon by the cams, whereby upon arelatively different adjustment of the screws in relation to the respective cams,the rocking member may be tilted to a greater or less extent to gradually increase the gap between sizing elements; a plurality of receiving members; and a selecting chute, movable relative,- ly to the sizing elements and synchronously with the rotation of the cams for tilting the rocking member, to conduct to a selected receiving memher the article passing the sizing elements, one end of said chute being always in communication with the sizing gap, the other end passing successively 115 into registration with the receiving members.
